PRESERVE-CANS.

Specification forming part of Letters Patent No. 141,994, dated August 19, 1873 application filed April 12, 1873.

To all whom it may concern:

Be it known that I, JOHN K. OHAOE, of the city of Brooklyn, county of Kings, State of New York, have invented a new and useful Improvement in Preserve-Vessels; and I do hereby declare the following. to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings mak in g part of this specification, in which Figure l is'a central vertical section of the device embodying my invention. Fig. 2 is a top view, partly sectional. Figs. 3 and 4 are vertical sections of detached parts.

Similar letters of reference indicate correspondin g parts in the several figures.

This inventionconsists in forming the ends of the body of a can or pail, respectively, with a tongue and a V or U shaped groove, the tongue and groove fitting each other and leavin g a channel for the-solder. It also consists in forming the cover with a channeled rim, embracing the top of the can and projecting downward around the same within a band of soft metal, which is then turned over the rim of the cover. It also consists in the construction of the bottom of a can or pail with an inward bead in connection with a flat head or disk.

Referring to the drawings, A represents the body of a can or pail, which may be constructed of any suitable metal, and of cylindrical or other form. One end of the piece constituting the body is formed with an oblique or angular tongue, to, and the other end with a V or U shaped groove, 1), the tongue entering the groove so as to leave a channel, 0, which will be filledwith solder, which flows around the edges of the'two parts, thus forming a superior seam, and one in which inferior metal can be used Without danger of breaking.

Since tongues and grooves of the same con struction and location can be produced on each can or pail, it is evident that the cans or pails will be of uniform size.

B represents an outwardly-formed bead nearthe top of the can or pail, and the edge is thrown inwardly at d; and 0 represents a ring, rim, or band of malleable or soft metal, which is so formed as to fit over the bead B and project above the edge d of the can or pail, so as to leave a space, 0, between the edge d and said ring G. A suitable cement or packing is to be introduced into the space 0, and a lid, F, having a channeled rim, h,

is placed over and upon the top edge of the can, so that the channel embraces the said top edge, and the edge of the rim projects into the space 0. The upper portion of the ring 0 is now turned or thrown down upon the lid F so as to completely overlap its circumference, thus forming a perfectly tight joint and holding the lid in place, as seen in Fig. 1.

When the lid is to beopened or removed, a blade or other convenient instrument is slipped under the turned-down edge of the ring 0, between said edge and the lid F, and the ring will be readily extended to its vertical position, whereby the lid F is accessible and easily removable.

It will be seen that neither the ring, body,

or lid is in anywise injured, and the parts are in condition for successive usage.

The lid 'F may be constructed of metal, Wood, or other material.

Should the lid F not be required, the ring 0 may be turned down on the top edge of the body A, and thereby produce a neat finish of the latter.

G represents an inwardlyformed bead near the bottom edge of the can, and to the bottom will be applied a flanged head or disk, whose edge is adapted to enter the external groove formed by the bead. When said edge is prop-' erly turned in, the bottom of the head or disk is rounded and leaves a channel, g, above the extreme edge of said head or disk for the reception of solder, which will flow around the said edge, between the same and the adjacent portion of the body of the vessel, whereby a tight and reliable joint is formed, less solder is required, there is no breaking of the metal, and the bottom is perfectly flat.

Having thus described myinventiomwhat I claim as new, and desire to secure by Let ters Patent, is

3. The inward bead G, in combination with a flanged fiat bottom, substantially as and for the purpose set forth.

The above signed by me this 13 day of March,

JOHN K. OHACE.
